Bukho Stone Feasibility (Nias) As A Layer Subbase Course on The Pavement

Authors(1) :-Oloan Sitohang

North Nias regency contains a significant amount of rock aggregate deposits, namely Bukho stone. To optimize the potential of the material source of the road, it will be conducted the Bukho stone feasibility test as the bottom layer material (subbase course) on the pavement.This study aims to find out whether the bukho stone is eligible and suitable for use as a subbase course material of road pavement according to SNI 03-6388-2000 and laboratory CBR value. The tests are: Sieve Analysis, Abrasion (SNI 03-2417-1991), Liquid Limit (SNI 03-1967-1990), Plastic Limit (SNI 03-1967-1990), and Plasticity Index testing (SNI 1966-2008). Then testing Modified Compaction (SNI 03-1743-1989), resulting in a graph of the relationship of dry weighted (?d) and optimum water content (wopt). Furthermore, testing support of materials by means of CBR laboratory (SNI 03-1744-1989). The result of the research is Abrasion of 28,44%, Plasticity Index 1,056%, Laboratory CBR value on gradation A, B and C respectively 58,33%, 40,68%, and 20,34% meet the minimum requirement of CBRsubbase course that is ? 20% according to the guidance of thickness planning of the bending of the highway pavement (SKBI 378 / KPTS / 1987). While on the gradations of D, E, and F obtained the value of CBR laboratory respectively of 15.149%, 18.87%, and 15.439%.Bukho stone test results can be used and feasible as subbase course materials using gradations A, B, and C.
